This document provides commentary on Isaiah 31 from multiple scholars. It discusses the sin of relying on Egypt for help rather than trusting in God. The Israelites went down to Egypt for military assistance with horses and chariots against the Assyrians, despite being forbidden to do so. They did not seek God's counsel or make Him their friend. Relying on human strength and allies goes against relying on the Holy One of Israel, who is all-powerful and wise. Egypt and its forces are merely mortal while God is immortal.
